OJB XDoclet generating torque table schema

[Hayes, Reggie D.]

I am using the xdoclet ojb module to generate an ojb repository and a torque
schema.  The problem that I am running into is that the foreign key
reference constraints are not generated for collections.  My persistent
collections are only implementing 1:n associations.  The foreign key
reference constraints are generated for references.  Am I doing something
wrong?
